In their first season without club veteran and captain Michael Carrick, 2018/19 was a damp squib for Manchester United. They finished 6th in the Premier League with 66 points – 32 points fewer than rivals Manchester City in 1st.
Jose Mourinho was sacked midway through the season, triggering the return of club legend Ole Gunnar Solskjaer as interim manager, a position that became permanent after a few months of brilliant results during which United won 10 out of 12 games, drawing the other 2. However, they took just 2 points and scored only 2 goals from their last 5 games of the season.
They made it to the Quarter finals of the Champions League before being roundly beaten in both legs by Barcelona, and a last minute goal from Marcus Rashford against Wolves wasn’t enough to get them further than the Quarter finals in the FA Cup either. Their EFL Cup campaign lasted just one game, which they lost on penalties to Derby.
